Lexus’s third generation IS sports saloon is offered in two versions: the turbo petrol

powered IS 200t and the full hybrid IS 300h. The 200t debuted in the range in

September 2015, joining the IS 300h, the first IS to be equipped with Lexus Hybrid Drive.

Both models are rear-wheel drive and available with a dedicated F Sport styling and

handling package.

Every aspect of the IS is engineered to deliver a rewarding ownership experience,

recognising the importance customers in this part of the market place on driving

performance.

The IS also showcases a dramatic design, led by a new interpretation of the Lexus

spindle grille; an interior with a more focused, sporting environment for the driver and

significantly more rear seat space; and a larger, more convenient luggage compartment.

Development conceptThe IS has been engineered for sporting performance, agile handling, accurate

responses and excellent feedback to the driver.

The exterior styling features a specific interpretation of Lexus’s spindle grille design,

giving the IS greater road presence and a stronger brand identity.

The interior maintains the refinement and quality that are fundamental to Lexus, but

introduces a more sporting, focused environment for the driver. Best-in class

accommodation has been achieved with a significant improvement in rear-seat knee-

room; the boot has also been made larger and more user-friendly.

The IS’s driving dynamics have been painstakingly engineered to help deliver the best

possible driving enjoyment – a principal goal in the car’s development programme.

New laser screw welding and adhesive body bonding techniques and extra spot welding

have increased overall body rigidity, while revisions to the double wishbone front

suspension have brought about a 20 per cent increase in roll rigidity. There is a new

multi-link rear suspension, similar to that used by the Lexus GS.

A Drive Mode Select system lets the driver choose between up to five modes – Eco,

Snow, Normal, Sport/Sport S and Sport S+ (the latter on the IS 300h F Sport fitted with

optional Adaptive Variable Suspension) – to achieve their preferred balance of economy,

comfort, performance and handling characteristics. On the full hybrid IS 300h there is

also an all-electric EV mode.

The IS F Sport models not only come with exclusive styling elements, inside and out,

they also gain genuine dynamic enhancements thanks to retuned front and rear

suspension. The IS 300h F Sport additionally comes with optional Adaptive Variable

Suspension.

The full hybrid IS 300h’s drivetrain combines a powerful electric motor with a 2.5-litre

four-cylinder Atkinson cycle petrol engine. The engine features D-4S fuel injection

system, Dual VVT-i intelligent variable valve timing and a high-efficiency exhaust gas

recirculation system. In the IS 300h SE the system delivers 97g/km CO2 emissions and

combined cycle fuel consumption of 67.3mpg, following its homologation to Euro 6

emissions standards in spring 2015.

Lexus offers several new active safety features on IS, including a Blind Spot Monitor with

Rear Cross Traffic Alert (on Premier grade models).

All models are equipped with a pop-up hood design that creates space for better

absorption of pedestrian impact forces while also maintaining the lowest possible front

profile for the vehicle.

DESIGN AND PACKAGING All-new exterior with Lexus spindle grille and L-shaped daytime running lights

Rear wheel arch hemming treatment and laser-brazed roof structure enhance the

elegant look

LFA-inspired driver cockpit

Significantly more rear seat space, 60:40 split-folding rear seats (excluding IS 300h

SE), and uncompromised luggage capacity

Exterior designThe advances made in the IS’s dynamic capabilities and driving performance are

reflected in the car’s powerful design, with its sleek surfacing and tight, sporting

proportions.

Measuring 4,665mm overall, the model is 75mm longer than its predecessor. Just 5mm

have been added to the front overhang, while the wheelbase has been extended by

70mm to 2,800mm. The car is 10mm wider than before, too.

Following the precedent of the latest GS and LS models, the IS gains the sophisticated

dynamism of Lexus’s spindle grille frontal design, giving greater road presence and a

stronger brand identity.

The grille has been given a stronger three-dimensional quality, its shape accentuated by

a chrome-plated frame and projection of its upper horizontal bars in a line that follows

the curvature of the front of the vehicle.

The grille is flanked by headlamp clusters which, true to Lexus’s hallmark design

characteristic, are set on a higher plane than the grille itself. The result is to focus the

eye on the apex of the vehicle, giving the design a resolute look and strengthening the

overall impression of power and agility.

The powerfully articulated headlamp units have a single projector design; all models

feature high-intensity discharge (single xenon) lamps. In another first for a Lexus model,

the LED daytime running lights are located independently beneath the cluster. Set in the

trademark Lexus L-shape, they give the IS a distinctive visual signature.

The deep front bumper design anchors the muscular front wings and flared wheel

arches. The integral fog lamps are housed in secondary, sculpted side air intakes which

control the flow of air through the wheel arches, improving the vehicle’s aerodynamic

performance.

The overall dynamic shape of the body is generated by the spindle grille: it widens

across the bonnet, passes through the base of the front pillar, then tightens as it flows

towards the rear. Not only does this clearly delineate the body from the cabin, it also

emphasises the wide flare of the wheel arches.

In profile, the strong horizontal belt line creates the impression of larger rear tyres and a

lowered centre of gravity. The mass of the cabin appears to be concentrated rearwards,

suggesting more weight over the rear tyres and the perception of greater traction. A

rising crease line flows from the lower body, through the rear wheel arch into the rear

lamp clusters, adding further dynamism to the saloon’s profile.

The rear lamp clusters incorporate an aero-stabilising fin – a small but telling detail in

smoothing airflow and promoting better handling – and feature the familiar Lexus L motif.

The clean, coupe-like lines are further enhanced by two Lexus firsts: a hemming

treatment for the rear wheel arches that allows the tyre to be placed further outboard,

closer to the wheel arch; and a laser-brazed roof structure which joins the roof and side

members without the need for a roof drip moulding.

Interior designThe clean, horizontal theme of the IS’s interior design is bisected by the strong upward

sweep of the centre console. This creates a snug, focused and ergonomically ideal

environment for the driver.

The quilted finish to the driver’s seat gives greater comfort and lateral support; the seat’s

hip point has been lowered by 20mm. The three-spoke steering wheel is inspired by

Lexus’s LFA supercar and has reshaped paddle shift switches for easier and more

accurate operation. The wheel-mounted switchgear also displays an improved

ergonomic design.

The steering wheel angle has been lowered by three degrees and its reach adjustment

has been increased by 23mm, creating a more sporting driving position. At the same

time, the windscreen wiper rest position has been lowered by 15mm, so the driver can

enjoy the same angle of vision as in the previous IS.

Rear seat occupants enjoy a more comfortable environment thanks to 50mm of the

70mm increase in the wheelbase being dedicated to extra space in back. The longer

wheelbase and a thinner front seat design combine to give 85mm more knee room,

while an extra 20mm in the gap between the centre pillar and the front corner of the rear

seat makes for easier access.

Because the hybrid battery is located beneath the luggage deck board, filling a space

normally occupied by a spare wheel, there is 450 litres of load space (compared to 480

litres in the IS 200t). Extra space has been gained in all versions, thanks to a 20mm

increase in load compartment length.

Throughout the interior the use of high quality materials and finishes conveys a

contemporary, premium look and feel, with the craftsmanship and attention to detail for

which Lexus is renowned. Soft-touch finishes abound, including kneepads either side of

the centre console in the F Sport models.

The silver metallic trim detailing on the instrument meter is complimented by a precision-

machined analogue clock with surface-emitting illumination.

Human-oriented interior design is a fundamental part of Lexus’s L-finesse design

philosophy, reflected in the way the IS’s dashboard is divided into distinct display and

operation zones.

The upper display zone houses a seven-inch LCD multi-display screen, set at an ideal

distance for at-a-glance viewing from the wheel. The lower operation zone gives access

to system controls, including Lexus’s second generation Remote Touch Interface.

The IS follows the latest GS and LS in adopting a Drive Mode Select system, and a

change in meter illumination from blue to red when sports driving modes are engaged,

along with the automatic switch from a hybrid system indicator to a tachometer in the IS

300h F Sport.

Lexus’s first electrostatic switches for controlling the air conditioning are located in the

centre console, operated with just a touch of the finger. Models are equipped (according

to grade or option specified) with either the Lexus Media Display or Lexus Premium

Navigation pack; the steering wheel is the first in a Lexus to co-ordinate multimedia

system control with both meter and centre console displays.

Wheels, colours and trimsFour alloy wheel designs are offered with five-spoke 16-inch rims standard on the SE

models, 17-inch 10-spoke for the Luxury, 10-spoke 18-inch for the F Sport and five-

spoke 18-inch for the Premier grade.

Ten exterior paint finishes are available: Arctic Pearl, Satin Silver, Sonic Titanium,

Mercury Grey, Mesa Red, Ultra Blue, Atlantic Blue, Velvet Black (solid) and Celestial

Black, plus the grade-exclusive F Sport White.

Sonic Titanium uses a new advanced coating process developed by Lexus engineers to

give a more radiant finish. An additional metallic texture provides strong shading and

sharply defined highlights, making the bodylines more noticeable and the surfaces finely

polished.

According to grade, seats are finished in a combination of black fabric with Tahara

bolsters (SE, Luxury and F Sport) or black leather (Premier). Leather can specified for

the Luxury (ivory, grey or black) and F Sport models (black and Dark Rose).

ON-BOARD TECHNOLOGY Dual-zone air conditioning with touch-sensitive electrostatic switches

Lexus Media Display and Lexus Premium Navigation systems with Remote Touch

Interface

Lexus-first steering wheel co-ordination of multimedia system with both meter and

centre console displays

Mark Levinson Premium Surround System with new loudspeaker technology

Dual-zone air conditioning with electrostatic switches

The new IS’s dual-zone air conditioning system incorporates a compact, high cooling

performance expansion valve. Power usage has been greatly reduced, which

contributes to better fuel economy.

It is controlled using Lexus’s first electrostatic switches: sliding a fingertip up or down the

bar-shaped switch will adjust temperature in half-degree Centigrade or one-degree

Fahrenheit increments. Alternatively, adjustments can be made by pressing the arrow

markings on the top and bottom half of the switch.

The air conditioning also has a customised blower function, so users can set a default

airflow when the system is on auto, choosing from fast, medium or soft settings. A new

full-screen display in the Lexus Media Display has been added to confirm the operating

status.

Advanced multimedia systemsTwo multimedia systems are available, both working in conjunction with a high-resolution

seven-inch full colour display.

The Lexus Media Display (standard on SE, Luxury and F Sport grades) is operated

using an eight-way joystick control.

The new generation Lexus Premium Navigation (standard on Premier grade and an

option on all others) provides USB, Aux, Bluetooth and WiFi connectivity and improved

HMI features. Steering wheel controls can be used to co-ordinate control of the system

with both the 4.2-inch meter and seven-inch centre console displays.

Enabling the Lexus Premium Navigation system to be linked to the monitor in the meter

display allows the driver to view audio data, mobile phone reception and incoming call

information, as well as navigation directions. The cross switch on the steering wheel can

be used to select music tracks and place outgoing calls.

The integral navigation system’s CPU has about four times the processing power of the

previous system. It provides automatic screen zoom at intersections and a number of

advanced functions including a true 3D view with city model and landmark graphics;

accurate replication of motorway signage; speed limit information; and a new Doppler

Weather Radar display.

Access can be gained to an on-line Points of Interest search from Google Local Search,

with connection via a Bluetooth mobile phone. This also allows addresses from Google

Maps to be downloaded as navigation destinations.

Lexus Connected Services has collaborated with INRIX to provide the new IS with the

world’s first parking navigation service, with real time traffic and parking services fitted as

standard.

Lexus Connected services also provide two new Google link functions: Google Street

View and Panoramio, a photo-sharing service that allows images to be uploaded for

viewing on the centre console display.

Second generation Remote Touch InterfaceThe Lexus Premium Navigation is operated using the second generation of Lexus’s

Remote Touch Interface multi-function control, which has been revised for easier, more

intuitive operation.

It uses the world’s first slide haptic joystick mechanism – a slide-type controller that is

much like a computer mouse, helping users scroll quickly and easily across the display

screen. The enter command is now made simply by pushing the controller. Adding

ambient lighting and minimising the height difference between the controller and the

armrest have helped make it easier and more comfortable to use.

Premium sound systemA Premium Sound System is fitted as standard to the SE, Luxury and F Sport versions of

the IS, featuring a fully digital, Class-D, eight-channel amplifier that creates virtually

distortion-free sound with minimal voltage losses. The natural sound dynamics and rich

harmonies generated by the high definition amplification are faithfully reproduced by an

improved eight-speaker layout with a new 55mm wide-range tweeter.

The system provides better functionality and interface quality for connecting digital music

players such as iPods. Using a USB port, an iPod menu can be accessed using

switches on the steering wheel, with album cover art displayed on the 4.2-inch meter

display.

Mark Levinson Premium Surround SystemA Mark Levinson Premium Surround System is fitted as standard to the

IS Premier models and can be specified as an option on F Sport models. Mark Levinson

has worked in exclusive collaboration with Lexus for the past 12 years, engineering

sound systems to suit the specific acoustic qualities of each individual model.

The IS’s system was four years in development. It creates sound based on the concepts

of Effortless Dynamics and Effortless Transient Response, which combine natural

dynamics with high response and tracking performance to deliver sound quality

equivalent to a live concert hall performance.

Using the same technologies as those found in top-end home audio systems, it features

a 12-channel, fully digital Class-D amplifier generating 835 Watts through 15 GreenEdge

high-efficiency loudspeakers. The Auto Volume system automatically adjusts volume for

each track to ensure consistent levels and full audibility for even the quietest passages

of music.

All 15 speakers use power-saving GreenEdge technology, developing twice the volume

for the same power consumption. GreenEdge covers a wider frequency band than

conventional systems, giving an enhanced dynamic range.

Three 90mm GreenEdge speakers are mounted at the front of the cabin, with Unity

technology which integrates mid and high-range units within the same structure. Two

further 90mm GreenEdge units at the rear feature Wide Dispersion technology, with

built-in acoustic lenses to disperse sound more evenly throughout the cabin. Together

these five speakers give consistent timbre for both front and rear seat occupants,

resulting a new a level of surround sound, definition, atmosphere and quality.

A 200mm GreenEdge subwoofer uses the latest Inverted Motor Structure technology, in

which the magnetic circuit s mounted in an inverted position, significantly reducing the

depth of the unit with no loss of power or acoustic performance, while offering significant

space savings in system packaging.

POWERTRAINS IS 300h, the first IS to feature Lexus Hybrid Drive, incorporating a new 2.5-litre

Atkinson cycle petrol engine

CO2 emissions from 97g/km and fuel consumption from 67.3mpg (IS 300h SE)

Sequential Shiftmatic with paddle shift controls on the IS 300h, giving a manual

transmission shift feel for a more engaging driving experience

IS 300hThe IS 300h reinforces Lexus’s commitment to the future of hybrid drive technology. It is

powered by the latest generation Lexus Hybrid Drive, which achieves significant

reductions in fuel consumption CO2, NOx and particulate emissions, with no loss of

performance. Gains in emissions and fuel efficiency were achieved with the system’s

homologation to Euro 6 standards in spring 2015.

The full hybrid system combines a 105kW/141bhp electric motor with a new 2.5-litre,

133kW/178bhp four-cylinder Atkinson cycle petrol engine, equipped with next-generation

D-4S fuel injection, Dual VVT-i intelligent variable valve timing and high efficiency

exhaust gas recirculation.

The system drives the rear wheels via an electronically controlled continuously variable

transmission. Total system output is 164kW/220bhp, enabling nought to 62mph

acceleration in 8.3 seconds (IS 300h SE) and a 125mph top speed. Combined cycle fuel

consumption is from 67.3mpg with CO2 emissions of 97g/km (IS 300h SE) – among the

lowest in the car’s class.

Lexus Hybrid Drive system architectureAs with all Lexus hybrids, the IS 300h is a full hybrid that can be driven in petrol or purely

electric modes, as well as a combination of both. Its Lexus Hybrid Drive features a new

178bhp/133kW. 2.5-litre, four-cylinder petrol engine mated to a compact, high-output

141bhp/105kW water-cooled permanent magnet electric motor. The two powerplants

drive the rear wheels both independently or in tandem, as conditions require.

In addition to the petrol engine and electric motor, the hybrid drive system also

comprises a generator, a high-performance nickel-metal hydride battery, a power split

device which combines and reallocates power from the engine, electric motor and

generator as required, and a compact power control unit that governs the high-speed

interaction of the different components.

2.5-litre Atkinson cycle petrol engine

The 2,494cc four-cylinder petrol engine has been developed specifically for the IS

300h’s hybrid powertrain. It benefits from several advanced technologies and uses the

Atkinson cycle to optimise Lexus Hybrid Drive’s fuel efficiency.

In an Atkinson cycle engine, compression and expansion are not symmetrical; the valves

close late, delaying compression. This creates a high expansion ratio for less

compression, reducing intake and exhaust energy losses and converting combustion

energy to engine power more effectively.

A new exhaust gas recirculation system, with a high efficiency, large capacity cooler and

high response valve, reintroduces precisely measured exhaust gas, cooled from around

700 to 130°C into the intake system, via a stainless steel exhaust manifold. This further

reduces engine operating temperatures while also reducing engine pumping losses by

bringing down intake vacuum pressure.

Together these technologies minimise the situations when fuel enrichment is needed to

protect the catalytic converter from overheating damage, thereby improving fuel

economy and emissions.

Further reductions in fuel consumption have been achieved through a high physical

compression ratio of 13.0:1; by optimising the shape of the intake port and combustion

chamber; the use of low friction piston rings, roller arm type valve gear and a variable

discharge volume oil pump; and the adoption of next generation D-4S direct injection

technology.

D-4S is the latest evolution of Lexus’s stoichiometric, four-stroke direct injection

technology. With one injector in the combustion chamber and a second in the intake

port, it combines the strengths of both direct and port injection, realising optimum engine

efficiency across the power band and improving torque at all revs, while minimising fuel

consumption and emissions.

The D-4S system uses new slit-type injector nozzles with an optimised injection hole

shape; a higher, 18MP injection pressure for more efficient combustion; and idle port

injection that improves NVH performance.

Using Dual VVT-I intelligent variable valve timing on both intake and exhaust camshafts

also significantly improves engine performance. Being able to control the camshafts

through angles up to 40 (intake) and 35 (exhaust) degrees, the system permits a greater

overlap of the intake and exhaust valves. This benefits low and top-end torque as well as

contributing to a reduction in exhaust emissions and better cold-start performance.

Engine noise, vibration and friction have also been lowered by using a low friction timing

chain, a highly elastic stretch belt, optimisation of the crankshaft shape and balance

shaft, and the use of plastic gears.

Hybrid transaxleThe electric motor, electric generator, power slit device and motor speed reduction

device are housed in a single, lightweight and very compact transmission casing that is

comparable in size to a conventional gear box. This transaxle is the heart of Lexus

Hybrid Drive.

The seamless electronically controlled continuously variable transmission can be

switched to a sequential shiftmatic mode, operated using paddle shifts on the steering

wheel, giving a manual shift feel for a more engaging driving experience.

Electric motorThe 105kW high performance electric motor (permanent magnet, synchronous type)

works in tandem with the petrol engine to boost acceleration, and powers the driven

(rear) wheels on its own when the vehicle is running in EV mode. During regenerative

braking, the motor also operates as a high-output generator, recovering kinetic energy

as electricity to charge the hybrid system battery.

The motor generates a maximum 300Nm of torque, boosted through a reduction gear in

the transaxle. This significantly enhances acceleration from standstill.

GeneratorLike the electric motor, the generator is AC synchronous. It performs a number of

different functions within the Lexus Hybrid Drive system.

As the system doesn’t have a starter motor, the generator is used to start the petrol

engine. In normal driving conditions, engine output is divided according to system

requirements, both to drive the wheels and power the generator, which, via the power

control unit, drives the electric motors and simultaneously charges the high-voltage

battery. Moreover, the generator is also used to control engine speed for maximum fuel

efficiency.

When there is no call on the engine from the hybrid system, the generator is used to

stop it. But if the IS 300h runs on its electric motor long enough to require battery

charging, the generator will automatically start the engine, which itself provides the

power for the generator to charge the battery.

High-output batteryThe Lexus Hybrid Drive’s 230V battery uses proven and reliable nickel-metal hydride

technology and enables the IS 300h to be driven in EV mode, using electric motor power

alone.

For the first time in a Lexus, the hybrid battery has been installed in a reinforced

compartment beneath the loadspace floor, without compromising the space available for

luggage.

Power control unitThe power control unit is little larger than a 12V battery. Modifications to its structure and

materials have reduced its weight and size; the PCU in the new IS 300h is 20 per cent

lighter than before.

The unit consists of a voltage boost converter, which boosts the electric motor, generator

and battery voltage to increase hybrid system power output; a highly compact inverter

for the motor/generator, which converts DC power from the battery into 650V AC power

for driving the electric motor and, occasionally, the generator; and a DC/DC converter,

which reduces the high voltage of the hybrid system battery to 12V, supplying power to

the accessory systems and charging the auxiliary battery.

Lexus Hybrid Drive in operationOver the course of any journey Lexus Hybrid Drive operates in different modes to

maximise efficiency. At rest the engine automatically stops to conserve fuel. When

efficiency is at its lowest, such as at start-up and at low to mid-range engine speeds, the

IS 300h will run on its electric motor alone, eliminating CO2, NOx and particulate

emissions.

In normal driving conditions, the allocation of power is constantly adjusted between the

engine and electric motor to achieve the best balance of performance and fuel efficiency.

The electric motor acts as a high-output generator during deceleration and under braking

to effect regenerative braking; this optimises energy management by recovering kinetic

energy (that would usually be lost as heat) as electric power for storage in the hybrid

system’s battery.

At all speeds Lexus Hybrid Drive monitors itself to ensure the best combination of

performance and fuel efficiency with least emissions, either running the electric motor or

engine alone, or together. The level of battery power is constantly managed by using the

engine-driven generator. This means the system doesn’t have to be recharged using an

external power supply.

As fully described in the Driving Dynamics section below, the IS 300h has a new Drive

Mode Select system, increasing the vehicle’s capabilities beyond the Normal driving

mode. An EV mode permits near-silent running on electric motor power alone, which

means zero fuel consumption and tailpipe emissions. An Eco mode maximises efficiency

and fuel economy; Sport/Sport+ mode boosts full hybrid system performance, while a

Snow mode modulates throttle response to give better traction and stability when pulling

away on slippery surfaces.

Sequential ShiftmaticThe E-CVT can be switched to a sequential shiftmatic mode using paddle shifts on the

steering wheel. The system has been tuned so there is a closer match in the increases

in engine and vehicle speeds, and to deliver engine braking force in six steps under

deceleration, with a shift feel like that of a manual transmission.

Active Sound ControlThe driving experience is further enhanced by another Lexus-first, Active Sound Control.

This new technology complements the sound of the engine with an audio feed through a

dedicated loudspeaker. Active Sound Control delivers the sound of acceleration and

deceleration, even when the engine in the hybrid system is switched off and the car is

being powered only by the electric motor. It is automatically deactivated when Eco or EV

mode is selected.

IS 200tThe Lexus IS saloon adopted petrol turbo power for the first time with the introduction of

the IS 200t. It is the third model to be announced with the new Lexus engine, following

the NX 200t crossover, and the forthcoming new RX 200t SUV.

In the IS the 2.0-litre unit delivers 241bhp (180kW) and maximum torque of 350Nm. It

gives rapid acceleration up to a top speed of 143mph, driving the rear wheels through an

eight-speed Sport Direct Shift automatic transmission that was originally developed for

the RC F high-performance coupe. Nought to 62mph acceleration can be achieved in

seven seconds, while official combined cycle fuel consumption is 39.2mpg

The engine benefits from a raft of innovations and technologies that secure, fast throttle

response, instantaneous torque, minimal turbo lag and strong fuel economy. Key

elements include D-4ST fuel injection and a water-cooled cylinder head with integrated

exhaust manifold and twin-scroll turbocharger.

Innovative engine technologiesLexus has used a world-first combination of engine technologies to achieve a high level

of responsiveness, minimal turbo lag and good low-speed torque, together with excellent

fuel economy.

The four-into-two exhaust manifold pairs cylinders according to their expansion or

compression stroke. This innovative structure acts in conjunction with the highly efficient

twin-scroll turbocharger and prevents interference between the exhaust gases from each

cylinder, generating high torque across the widest possible rev range.

The engine also uses an air-to-liquid intercooler mounted directly on the engine,

significantly reducing the intake volume downstream of the turbo, so minimising turbo lag

and securing highly responsive performance.

The twin-scroll turbocharger itself features variable waste gate valve control. This

minimises pumping losses by reducing back pressure during low engine loads when the

turbo isn’t required.

D-4ST fuel injectionD-4ST uses a high pressure fuel system for injection directly into the cylinders and a low

pressure system for port injection. Injection is split between the direct and port injectors

according to engine load, optimising fuel combustion in all driving situations to improve

both low-speed torque and fuel economy.

It works in combination with turbocharging technology to create a high level of

compatibility between the high tumble ratio (achieved by optimising the shape of the

cylinder head intake ports and the piston tops) and the turbo boost control.

Dual VVT-iW technologyThe turbo engine features innovative dual intelligent variable valve-timing technology –

Dual VVT-iW. This allows torque to be optimised throughout the rev range and lets the

engine run at start-up on the Otto cycle, before switching to the more fuel-efficient

Atkinson cycle. The system applies VVT-i to the exhaust valves and VVT-iW to the

intake valves, and also allows for wide open throttle performance.

The late closing of the intake valve on the Atkinson cycle reduces pumping losses and

boosts fuel economy. VVT-iW incorporates a mid-position lock which enables the

Atkinson cycle to be maintained without sacrificing starting performance in cold weather.

Light weight and further advanced featuresThe engine is remarkably light and compact, weighing just 160kg. Cast with low nickel

content heat resistant steel, it features a cylinder head cover, intake manifold and intake

pipes formed in a resin material. The unit underwent more than 10,000 hours of bench

testing prior to covering more than a million kilometres in on-road trials.

A number of measures were taken to reduce friction losses in different parts of the

engine, helping improve fuel economy. These include using an offset crankshaft to lower

the piston thrust load; improved machining of the cylinder bore; and a surface treatment

for the piston skirts which reduces slide resistance. Low-tension piston rings have been

used and the weight of reciprocating parts has been reduced.

The engine uses a lightweight roller rocker valvetrain and a low-friction timing chain.

Low-friction materials have also been used for the crankshaft oil seals, and the flow of

lubricating oil has been optimised, with a variable discharge mechanism reducing the oil

pump flow.

Careful heat management inside the engine further improves fuel efficiency: a rapid

warm-up system for the cylinder block suppresses the flow of coolant into the block

when the engine is cold, and a piston-cooling oil jet control system cuts the oil supply to

the pistons to improve warm-up speeds.

Smoothness, quietness and turbo soundThe rigidity of the engine’s main structural components is optimised to suppress

vibration, and a balance shaft with resin gears is fitted to achieve even greater

smoothness.

New calcium-free lubricating oil helps prevent engine knock at low revs; the piston

cooling oil jet system further improves anti-knock performance.

The water-cooled intercooler provides strong advantages in acceleration from standstill,

and delivers a 0.3-second reduction in the 0-62mph acceleration time compared to an

air-to-air unit. The acceleration curve prioritises torque delivery at low speeds.

Turbo engines tend to be noisy when the throttle is closed – the effect known as “turbo

sigh”. Lexus has used an electric air bypass valve and resonator to greatly reduce the

characteristic turbo noise. As a turbocharged engine requires a smooth intake flow for

performance, Lexus’s engineers focused on creating special duct shapes that deliver

power without noise.

Eight-speed transmissionThe turbo engine is matched to an eight-speed Sport Direct Shift transmission with

paddle shifts – a unit originally developed for the RC F high-performance coupe. The

rear-wheel drive IS 200t is the first Lexus saloon to vary gear shifting in line with G-

forces.

The transmission automatically downshifts under hard braking on the approach to a

corner, then hold a lower gear through the bend for best control, and then selects the

most suitable gear on exit to give the driver greater throttle response.

DRIVING DYNAMICS New laser screw and adhesive body bonding techniques for a substantial increase in

overall body rigidity.

Use of hot stamped and high-tensile sheet steel and aluminium reduce body weight

by 10kg

Revised front suspension with 20 per cent increase in roll rigidity, new rear multilink

suspension for increased grip and stability

New electric power steering system gives lighter, smoother and more accurate feel

with greater feedback

New Drive Mode Select for IS, allowing vehicle operation to be optimised for

economy, comfort, performance or handling.

Adaptive Variable Suspension – an option on the IS 300h F Sport – allows ride

characteristics to be fine tuned

The principal aim of the IS development programme was to achieve a segment-leading

driving experience, but not at the expense of the quietness and comfort that are inherent

in all Lexus vehicles. To achieve this, every aspect of the car’s driving dynamics has

been painstakingly engineered.

The bodyshell is lighter but more rigid than its predecessor. The front suspension has

been revised and a new format adopted at the rear, to give better grip and response to

steering inputs. A new steering system offers a lighter, smoother and more accurate feel

with improved responsiveness and feedback to the driver.

The new Drive Mode Select system features up to five switchable driving modes: Eco,

Snow, Normal, Sport/Sport S and (on the IS 300h with optional AVS) Sport S+. Where

specified, the Adaptive Variable Suspension system lets the driver fine tune vehicle ride

with a choice of Normal or Sport S+ modes. A drive mode controller is used for selecting

Eco, Normal Sport/Sport S and Sport S+, while adjacent switches are used for engaging

EV and Snow modes.

BodyshellOverall bodyshell rigidity has been increased thanks to new laser screw and adhesive

body bonding techniques, along with additional spot welding. This improves stability and

body control while also allowing for a more comfortable ride without detracting from

handling agility.

Comprehensive use of body adhesives plays a major part in the IS’s improved handling.

Rather than joining panels at specific points, as with spot welding, the body adhesive

technique forms a bond along the entire surface of joined panels, maximising joint

rigidity. The new IS uses more than 25 metres of body adhesive, which has a significant

effect on body rigidity and the bodyshell’s vibration damping performance.

Laser screw welding is applied to the door apertures and upper back panel. This new

technique achieves a fine pitch that isn’t possible with spot welding, joining a larger

panel area and achieving better suppression of cross-sectional deformation.

Handling stability and steering response are further improved by the use of a new rear

subframe, cowl side braces to connect the front pillar and apron member, and

underbody rigidity measures including a new radiator support and optimised bracing to

the front and rear of the transmission tunnel.

Weight reduction was another important goal. Using hot stamped and high tensile steel

sheets for reinforcements and other critical components combines strength and

structural simplicity with weight-saving. Allied to the use of aluminium in other areas,

including the bonnet, this has helped make the bodyshell 10kg lighter than its

predecessor.

SuspensionThe IS has a revised double wishbone front suspension system and a new multi-link

system at the rear, similar to that used in the current generation Lexus GS. Both have

been tuned to match the driving feel of the saloon, giving improved ride comfort, grip and

response to steering inputs.

At the front, revisions have been made to the upper support hub and bearing, the anti-

roll bar and its link and bushing, and the lower arm. The anti-roll bar layout has been

revised and the bar’s rigidity has been increased by 20 per cent to reduce roll during

cornering. To compensate for this extra rigidity the coil spring rate has been lowered,

improving ride comfort.

Roll rigidity distribution has been increased to help optimise steering response and

stability during emergency manoeuvres. In addition, rigidity of the front lower arm No1

bushing has been doubled to improve yaw response during steering.

The new multilink rear suspension locates the coil springs and shock absorbers

separately. This increases shock absorber efficiency, giving better ride comfort. This

modified layout also increases the pitch between the suspension towers, giving more

space in the luggage compartment.

The multilink design has been substantially revised for installation in the new IS, with

changes to the upper and lower arms, toe control arm, upper support, shock absorber,

carrier, hub bearing and anti-roll bar.

The characteristics of the bushing and sliding parts in the shock absorber have been

optimised by using a lightweight, resin-free piston with a sliding ring. This achieves a 53

per cent reduction in suspension friction. Also, by locating the toe control arm at the

back, tyre grip has been increased by about 15 per cent when cornering.

SteeringThe quality of steering feel and feedback is fundamental to an enjoyable driving

experience. To this end, the IS’s new electric power steering benefits from a steering

gearbox based on that used in the latest GS, with a number of tuning measures.

With particular attention paid to achieving a clear sense of the neutral steering position,

the structure and rigidity of each component have been revised to achieve a lighter,

smoother and more accurate steering feel, with better response to inputs and feedback

to the driver.

The power steering gear’s stroke ratio has increased by about eight per cent, changing

the rack stroke per pinion turn to 55.6mm. The rack bushing rigidity has been increased

by four times over the precious model and rack end bushing wear has been reduced.

Using floating end bushings gives better response to minor steering adjustments. Within

the steering gearbox, the rigidity of the pinion gear support has been increased and the

ball screw structure has been modified for smoother motor torque transfer.

Together with these comprehensive improvements, the steering’s assist characteristics

have been optimised to enhance the vehicle’s dynamic performance and steering feel.

BrakesThe IS has a completely new brake system, designed for the quick response, linear

effectiveness and controllability appropriate for a Lexus sports saloon.

The IS 200t and IS 300h both use 296 x 28mm ventilated front discs; at the rear the IS

200t has 290 x 10mm solid discs, while those on the IS 300h measure 290 x 18mm. All

versions feature aluminium alloy callipers.

Experience gained engineering the Lexus LFA was used in the design of the compact,

lightweight master cylinder and stroke simulator. Brake booster power has been

optimised to enhance brake effectiveness and controllability, and the pedal shape, angle

and ratio have been changed so an instant response can be given to changes in pedal

force.

Better brake cooling performance has been gained by adopting straighter brake ducts

that give a larger cooling airflow volume, minimising brake fade, even under protracted

use.

Drive Mode SelectThe IS’s new Drive Mode Select system features up to five switchable driving modes:

Eco, Snow, Normal, Sport/Sport S and (on the IS 300h with optional AVS) Sport S+,

allowing the driver to adapt the vehicle for their preferred combination of economy,

comfort, performance and handling characteristics. A drive mode controller is used for

selecting Eco, Normal Sport/Sport S and Sport S+, while adjacent switches are used for

engaging EV (in the IS 300h) and Snow modes.

In Eco mode engine output, throttle opening and gear selection are automatically

modulated to optimise fuel efficiency in all driving conditions. The air conditioning system

temperature and airflow volume are also co-operatively controlled, further reducing fuel

consumption.

Snow mode adapts throttle response to gain the best traction and stability when pulling

away from start-up on slippery surfaces.

In Sport mode, engine speed and throttle responses are sharpened for a more engaging

driving experience and full exploitation of the IS’s capabilities – in the case of both petrol

and full hybrid powertrains.

Where Adaptive Variable Suspension is specified as an option on the IS 300h F Sport,

Sport S+ mode combines the enhanced powertrain output of Sport/Sport S with co-

ordinated control of the AVS and electric power steering to minimise body roll, sharpen

handling and optimise steering feel.

The IS 300h additionally offers EV mode, for ultra-quiet running on electric motor power

alone, giving zero fuel consumption and emissions.

The ambient lighting of the driver’s instruments changes to blue in Eco mode, and to red

in Sport/Sport S and Sport S+. And when selecting Sport/Sport S or Sport S+ modes,

the IS 300h F Sport’s system power indicator is automatically replaced by a tachometer.

Adaptive Variable Suspension

Adaptive Variable Suspension is available as an option on the IS 300h F Sport. The

system lets the driver tune the car’s handling characteristics with a choice of two damper

settings: Normal, for everyday driving comfort; and Sport S+, for improved body control

and precise steering responses when cornering.

The system automatically adjusts suspension performance at all four wheels

independently, in response to driving operation, vehicle body motion and road surface

conditions, activating the adjustable damping force shock absorbers to fulfil a range of

specific control functions.

When Sport S+ mode is selected, the system automatically increases the difference

between inner and out shock absorber damping through corners to further reduce

vehicle roll.

Intake Sound CreatorThe IS 200t F Sport features an intake sound generator which creates a more sporting

engine note. It uses a damper to amplify vibration of the intake pulse and introduces it as

a pleasing sporty note into the cabin.

F SPORT Exclusive exterior design elements, including new front-end treatment, LED fog

lamps and 18-inch wheels

Interior features sports seats with Lexus’s integrated foaming construction,

perforated leather steering wheel and gear lever finish and exclusive trim and colour

schemes

Driving dynamics enhanced with specific tuning of the suspension and electric power

steering

F Sport grade available for both IS 200t and IS 300h

DesignExterior featuresIS F Sport models are instantly recognisable thanks to their exclusive grille and front

bumper design. The waistline of the spindle grille design is set higher, increasing the

area of the lower grille so it can draw in a larger volume of cooling air, appropriate for

sportier driving.

The grille itself features an F Sport-specific mesh pattern and its lower section has a

more prominent chrome-plated frame.

LED fog lamps are integrated in the bottom corners of the front bumper, which also has

F Sport-exclusive aerodynamic detailing to improve downforce and brake cooling. The F

Sport 18-inch alloy wheels have a Y-spoke design and a dark metallic coated finish,

linking with the LFA supercar’s bloodline.

Interior featuresThe F Sport specification includes the innovative driver’s meter with moving centre ring

that was first seen in the Lexus LFA. In a Lexus first, the highly supportive front sports

seat design uses an integrated foaming construction technique that allows large concave

surfaces to be moulded, with no gaps between the seat upholstery and foam padding.

The result is excellent comfort and great lateral holding performance.

Bespoke interior trim details include an F Sport steering wheel and gear level covered in

perforated leather; metal film 3-D effect ornamentation, black seat stitching; and

aluminium pedals and scuff plates.

The seats have black fabric centre panels with black Tahara leather-effect bolsters as

standard; black or (exclusive to F Sport) Dark Rose leather upholstery can be specified

as an option.

Driving DynamicsThe F Sport models benefit from adjustments to the front and rear suspension and the

electric power steering to enhance handling without compromising ride quality. As

described in the Driving Dynamics section above, Adaptive Variable Suspension is

offered as an option on the IS 300h F Sport.

SAFETY AND DRIVER SUPPORT New features for IS include Blind Spot Monitor and Rear Cross Traffic Alert

Lexus-unique Vehicle Dynamics Integrated Management system

Use of high and ultra-high tensile steel in bodyshell provides excellent occupant

protection while also reducing vehicle weight

Lexus’s first Pop-Up Hood design provides better pedestrian impact protection while

maintaining a sleek, low front profile

The IS builds on superior safety standards set by its predecessor with the addition of a

number of new, advanced safety features.

Active SafetyBlind Spot Monitor and Rear Cross Traffic AlertA new Blind Spot Monitor (Premier grade models) uses a rear-mounted radar to detect

vehicles travelling in adjacent lanes that cannot be seen in the door mirrors. An indicator

light illuminates in the appropriate mirror to alert the driver when another vehicle is

detected in the blind spot. If the turn-indicator is operating while a vehicle is in the blind

spot, the warning light in the mirror will blink.

The same radar is used for a new Rear Cross Traffic Alert system (Premier grade). This

warns the driver of an approaching vehicle when reversing out of a parking place by

triggering a warning light in the corresponding door mirror and sounding a warning

buzzer.

Vehicle Dynamics Integrated ManagementLexus’s unique Vehicle Dynamics Integrated Management is featured on all IS models,

enhancing performance, traction control and vehicle stability.

VDIM uses comprehensive status data from sensors throughout the vehicle to integrate

operation of the ABS, Electronic Brakeforce Distribution, traction control and Vehicle

Stability Control (VSC) with the electric power steering.

Through this integrated control of all the elements related to vehicle movement, including

motor torque, brakes and steering, VDIM not only optimises the activation of braking,

stability and traction control systems, but can also further improve the vehicle’s kinetic

performance.

Where conventional active safety systems are only activated immediately after a vehicle

reaches the limit of its dynamic envelope, VDIM operates before that limit is reached.

This means the IS’s dynamic threshold limits are expanded, while gaining smoother

vehicle behaviour at the limit thanks to less obtrusive intervention by the active safety

systems.

Passive SafetyBody structureThe IS has been designed to achieve class-leading safety performance in frontal, off-set,

side-on and rear impacts.

Comprehensive use of high and ultra-high tensile steel in the body structure ensures

impact loads are channelled and absorbed to minimise cabin deformation in the event of

a collision.

Measures that help efficiently disperse forces from a frontal impact include a front pillar

reinforcement structure; a forward projecting rocker structure; and a high-tensile sheet

for the rocker outer and door inner reinforcement.

Particular attention has been paid to side impact protection, with ultra-high-tensile steel

used for the roof centre reinforcement and for rocker outer reinforcement over a wider

area. The inner side of the centre pillar is fabricated in high-tensile steel with hot press

sheet steel reinforcement.

Hot press sheet steel is also featured in the head rail outer reinforcement, with hot stamp

steel used for the front door impact beam. The sheet thickness of the rear door beam

has been increased and hard resin reinforcement has been added internally.

The rear bumper reinforcement is made using new electromagnetic foaming techniques.

The caulked structure eliminates the need for bolt fastening, combining energy

absorption efficiency with weight reduction. IS 300h models have a high-strength

bumper reinforcement and reinforcement bracing above and below the hybrid battery to

help protect it in a rear end collision.

Pedestrian protectionTo meet current pedestrian impact legislation would have required raising the level of the

new IS’s bonnet 40mm above the height of the previous model. But a new pop-up hood

design allows the lowest possible vehicle front profile to be maintained, while providing

excellent safety protection.

A sensor in the front bumper detects when a person collides with the front of the vehicle.

Actuators then immediately pop up the hood by about 70mm, creating extra space

between the bonnet and engine and allowing the bonnet to deform and absorb the

impact from the person’s head.

The high-precision sensors and control system ensure the pop-up hood will not deploy

should the car collide with a bollard, lamp post or other street furniture.

Further pedestrian protection measures include a readily deformable structure to the

front of the hood, reducing impact forces to the pedestrian’s thigh bone; a head impact-

reducing structure in the fender protector; and a break point in the cowl rear wall which

allows it to deform easily and almost completely.

AirbagsAll IS models are equipped with eight airbags: front (dual-stage), side and knee airbags

for the driver and front passenger and full-length curtain airbags.

The front airbags have variable force operation, deployed in line with the severity of an

impact, as measured by system sensors.

Technology PackLexus gives IS customers the opportunity to add a suite of advanced safety features and

driving aids to their vehicle in a Technology Pack option.

Available exclusively for the flagship Premier versions of the IS 200t and full hybrid IS

300h, the pack – a build-to-order option priced £1,540 – provides four additional

systems: -

Pre-Crash Safety system (PCS)

Adaptive Cruise Control (ACC)

Lane Departure Assist (LDA)

Automatic High Beam (AHB)

Pre-Crash Safety systemThe PCS system uses a millimetre-wave radar sensor that operates over a 20-degree

scanning radius to detect obstacles in the vehicle’s path, even when cornering.

Using a number of sensors, a pre-collision computer monitors vehicle speed, steering angle

and yaw rate inputs to help determine in advance whether an impending collision is

unavoidable. If there is a high risk of a collision, PCS will alert the driver with a buzzer and

warning on the multimedia display, activate the Pre-Crash Seatbelt pretensioners, and,

when the driver begins to brake, provide Pre-Crash Brake Assist to supplement the braking

effort. If the driver does not brake and a collision becomes inevitable, the Pre-Crash Brake

will automatically apply the brakes to reduce impact speed.

Adaptive Cruise ControlThe Adaptive Cruise Control works in two modes: constant speed control and vehicle-to-

vehicle distance control. Working at speeds above 31mph (50km/h), the constant speed

control operates just like a conventional cruise control system.

The vehicle-to-vehicle distance control can differentiate between vehicles directly ahead,

and those in an adjacent lane. It uses the PCS millimetre-wave radar sensor, allied to

constant speed, decelerator, follow-up and accelerator controls, to automatically slow the

car, match the speed of the vehicle in front and, once the road ahead is clear, accelerate

back to the previously selected cruising speed.

Lane Departure AlertThe Lane Departure Alert system monitors road markings using a camera mounted on

the rear-view mirror. If it detects the vehicle is deviating from its lane without the turn

signals being used, it alerts the driver by sounding a buzzer and showing a warning on

the instrument display.

Automatic High BeamThe Automatic High Beam function for the headlamps maximises night-time visibility by

automatically switching to low beam when the system’s camera detects the lights of an

oncoming vehicle, or one travelling ahead. This means the high beam can be used for

the safe maximum amount of time.

COST OF OWNERSHIP Lexus Hybrid Drive design for outstanding durability and low maintenance and

running costs

Lexus IS 300h SE delivers excellent fuel economy and emissions, 67.3mpg and

97g/km

The IS 300h has been engineered for durability and low maintenance requirements. For

example, the starter motor and alternator function are integral to the hybrid system and

need no servicing or replacement during the vehicle’s lifetime; and in place of a

conventional timing belt it uses a maintenance-free timing chain. The hybrid battery has

been developed with rigorous testing and is designed also to last the lifetime of the car.

With no need to service or replace these parts, customers can save significant sums in

component costs alone over a 60,000-mile period.

Lexus Hybrid Drive also has a positive impact on brake wear. Its efficient regenerative

braking system delivers the first half of all braking force, significantly reducing pad and

disc wear.

Tyre life is also greatly extended. Because hybrid vehicles run with higher pressures,

shoulder wear is reduced, while the smooth, linear power delivery and balanced vehicle

weight distribution reduce wear on front tyre treads.

The hybrid battery benefits from rigorous assessment for performance and durability,

supported by more than 15 years of in-service experience, and is designed to last the

lifetime of the car.

Tax benefits

Thanks to its sub-100g/km emissions performance, the IS 300h SE benefits from a

number of personal and business tax advantages, not least a zero annual road tax

(Vehicle Excise Duty) charge and advantageous benefit-in-kind rates.

Likewise a business adding the hybrid Lexus to its fleet will appreciate the lower VED,

fuel, insurance and service, maintenance and repair costs.
